Looking for a high gloss c hocolate cupcake frosting recipe

I've been working as a baker at my new/second workplace... totally out of my comfort zone, but I've been doing it for a few weeks now, and am surprised how comfortably I've settled into the role, especially since I hated it so much at the beginning. Anyway, last week I made a few hundred cupcakes for a wedding, and made a couple buttercream fostings, and a glossy choco ganache topping, and got so many lovely compliments, not only on the taste, but also on how well they looked. I personally thought the buttercream was too sweet, but I'm not a cupcake person, cannot honestly remember the last time I had a cupcake with frosting in my life. I've made cc's for my husband at home, but without frosting, because he mainly likes to taste the batter.. but can you blame him?

Anyway...I have to make more cupcakes on Thursday for another wedding, not sure what buttercream we're going to use yet, and might not even need a choco one, but I came across these pics, and would love to have the recipe in my file for future events.

I'm looking for a frosting exactly like this! not something like it, or close to it, but exactly like these pictures. if anyone knows the secret, please share, I would be extremely appreciative. Thanks.
